In order to research the steam gasification dynamics of the Shenhua Coal semi-coke and Shenhua Coal direct liquefaction residue semi-coke, with the C arbon conversion rate curve of the semi-coke steam gasification under different temperatures, the homogeneous reaction model (HM) and the non reaction shrinking co re model (SCM) were applied to simulate the steam gasification dynamics of the coal and residue and the Arrhenius equation of the coal semi-coke and the residue sem i-coke homogeneous reaction model and the non reaction shrinking core model was obtained.The comparison on the simulation results and the test numerical values sh owed that the homogeneous reaction model and the non reaction shrinking core model all could be well to simulate the steam gasification process of the coal semi-coke and residue semi-coke and the simulation results of the homogeneous reaction model would be better than the simulation results of the non reaction shrinking core mod el
